Abstract (en)

[origin: EP3675602A1] The present disclosure provides a power supply applied to multiple loads, an integrated power supply and a lighting fixture. The power supply comprises a first connector, at least one isolated power supply and at least one non-isolated power supply. The first connector is electrically connected with the at least one isolated power supply and the at least one non-isolated power supply, and is used for being electrically connected with a controller, in order to adjust power states of the at least one isolated power supply and the at least one non-isolated power supply by receiving a power supply control signal from the controller. The at least one isolated power supply and the at least one non-isolated power supply are respectively connected with corresponding load circuit, to supply power to the load circuits, and control working states of the connected load circuits according to the power states thereof. By integrating the isolated power supply and the non-isolated power supply in one power supply, not only safety requirement of the power supply is met, but also overall working efficiency of the power supply is increased.
